Provided are pigments having excellent heat resistance and volatility, compounds constituting the pigments, as well as pigment compositions, colored compositions, curable colored compositions, color filters, inks for inkjet printing, and processes for preparing radiation-sensitive colored compositions using them. A pigment represented by formula (I): In formula (I), R1 to R4 each independently represent alkyl, aryl, heterocyclyl, alkoxycarbonyl, carbamoyl, alkoxy, amino, a group forming a sulfonamide, a sulfonic acid ester or a sulfone, or cyano; R5 represents a hydrogen atom, alkyl, aryl or heterocyclyl; M represents a monovalent to trivalent metal; and L represents an anion or a ligand capable of coordinating with the metal. m represents an integer of 1 to 3; and n represents an integer of 0 to 2. The group included in the parentheses forms a monovalent anion as the entire group. |
